Studying esophageal pressure characteristics using high-resolution manometry: A comparison between solid state catheters and water-perfused catheters

Since the introduction of esophageal manometry in the mid 1950s many different
manometric systems have been introduced. The current gold-standard for
measuring esophageal pressure characteristics is the so-called high-resolution
manometry which refers to catheters with 1-cm manometric sensor spacing at the
position of the esophagogastric junction. Two different catheters are currently
available for clinical practice 1) catheters with water-perfused pressure
sensors, the so-called water-perfused catheters and 2) catheters with
solid-state pressure sensors, the so-called solid-state catheters. The current
classification for esophageal motility disorders as well as normal values for
high-resolution manometry have all been developed using solid-state catheters.
Normal-values for water-perfused high-resolution catheters are not available
and it is currently unknown whether pressure levels as measured by solid-state
catheters are different from water-perfused catheters.

Therefore, the aim of this study is to determine normal-values for esophageal
pressure characteristics using a water-perfused high-resolution manometry
catheter. Furthermore, we aim to compare pres
